tfm checksum mismatch signals possible font inconsistencies. Does
Matplotlib use its own fonts independent of the TeX fonts? Can it be
configured to use the fonts installed in TeX Live? Or you can symlink
Matplotlib fonts to your texmf-local which has higher priority. TeX
will then use Matplotlib fonts. If the encoding did not change, it
should work.
